Robin Williams' suicide not premeditated, says friend

A friend of Robin Williams' says the actor was "completely engaged" making plans about upcoming projects the day before he took his life last week, suggesting his suicide was a spontaneous act, according to TMZ.

Williams was found dead Aug. 11 in his Tiburon home with a belt tied around his neck.

TMZ reports that only hours earlier, Williams spoke with a friend, who declined to be identified, and asked questions about projects and seemed "completely engaged in the conversation," not offering any hint he was considering suicide, the friend said.

While the "Hook" actor seemed a bit down during the chat, that wasn't out of the ordinary for the 63-year-old, who "lived in a dark (emotional) place," the source said, adding "(Williams) was unhappy which he often was, but it was nothing unusual."
